- Exceptions *must* derive from BaseException.
- Integer division always returns a float. The -Q option is no more.
All the following are gone:
* PyNumber_Divide and PyNumber_InPlaceDivide
* __div__, __rdiv__, and __idiv__
* nb_divide, nb_inplace_divide
* operator.div, operator.idiv, operator.__div__, operator.__idiv__
(Only __truediv__ and __floordiv__ remain, not sure how to handle them
if we want to re-use __div__ and friends. If we do, it will make
it harder to write code for both 2.x and 3.x.)
- 'as' and 'with' are keywords.
